Extant genera and species of Microgastrinae
Dolichogenidea ate (Nixon 1973)
Subfamily: MicrogastrinaeGenus: Dolichogenidea
Original description (Nixon, 1973): Female. Has, like coniferae, a yellow hind tibia and yellow hind tarsus. The main differences between the two species have been contrasted in the key. Hind femur infuscate throughout. Stigma evenly dark brown; venation proximal to areolet fully pigmented. Head from in front markedly transverse (Fig. 43). Face strongly shining, virtually impunctate. Antenna fully as long as body; flagellum rather bristly; two preapical segments slightly more than twice as long as wide (Fig. 8). Mesoscutum strongly shining, impunctate. Suture between mesoscutum and scutellum somewhat deeply impressed in middle third and here with well defined costae. Between lateral polished zone of scutellum and shield proper, a narrow, parallel-sided furrow. Propodeum strongly shining and with a considerable amount of rugosity around the posterior orifice. Suture between postscutellum and propodeum deep, wide. Submediellan cell of hind wing large in proportion to size of vannal lobe; vannal lobe with conspicuous fringe throughout. Basal tergites (Fig. 67); apical, turned-over part of 1st tergite dull, rugose; sometimes a strong punctate element in rugosity. Basal field large, about three-quarters as long as rest of segment; its surface dull, with sculpture similar to that of 1st tergite but finer. Ovipositor weakly, evenly downcurved, about three-quarters as long as hind tibia, gradually widened from apex to base. Hypopygjum more weakly sclerotized than in coniferae and more produced at apex. Length: female, 3.2 mm without ovipositor; rather large species. Comments. This species is perhaps more closely related to longicalcar than to coniferae; it differs from longicalcar mainly in being larger, having more sculpture, slightly shorter hind spurs and a slightly shorter ovipositor.
